I've read on pedia about lighting rods. I read they prevent tall buildings and structures from getting struck by lightning and catch on fire. I also read they carry the lightning strike safety to the ground. But what does that really mean? Is it afterwards converted over to the power grid to be used as electricity or just simply carried to the ground and that's it?Do lightning rods already do this or has this never been done before? Is it even possible? I ask because lightning is a whole lot of electricity traveling in a split second. Wouldn't there need to be a lot of wiring to hold and carry the current? I would imagine there would be a lot of flickering lights with the sharp change in electricity on the grid and maybe more accidents that lightning rods actually prevents.Correct me if I'm wrong, but pedia does not mention lightning rods supplying electricity to the grid. I can't find the answer elsewhere. Anybody know?
if you smell smoke get out and worry about it later. but yeah i think they do if the building isn't ready to fall down but i help i answer your question..
You are both right. The American Red Cross does not make a big deal of the 'bare chest' issue, but the American Heart Association (and National Safety Council) does. Functionally, normal clothing does not interfere with CPR, but thicker clothing would. However, if an AED is used, or going to be used, then the bare chest is best. Bare chests also allow more accurate hand placement, better transmission of the forces, easier observation of breathes, etc. Every second counts as well. Taking even a minute to remove clothing worsens the victim's chances- about 10% per minute that goes by. This translates to basically ripping or cutting most things off.
I took CPR training last year and I don't remember hearing about any clothing removals being necessary. So yeah, I think you're right. Or you could just call 911 and start praying.
